All my sound levels are up to the full max. I have used audacity with this mic several times and no problem has occured. ( It sounds perfect) However I did stopped using audacity and mic for under a month because I was very busy. I did not changed any settings in this time. When I opened Audacity up and tried to record a song with my shure mic, it just left a straight line. I played it and there was no sound. (Please excuse me for my poor english.)
Here are some pictures on my settings.

This past week I have been playing with the settings hoping that something good may come up. Nothing at all.
Please help and suggest me some settings I should have on. Or just ask any question that comes out of your mind that may help.
I give you my dearest thanks.
